The Water Quality Committee and the Water Quality Staff have been proactive in the planning and preparation of our waterways since last year’s Harmful Algae Bloom (HAB).  Water quality sampling and monitoring has been ongoing for the duration of the season.  Unfortunately, the TKPOA is at the infancy stages of experiencing another algae bloom for this season in the West Channel, East Channel and Lake Tallac.  


Our sampling results show that the bloom is a type of cyanobacteria that is primarily composed of Dolichospermum. This cyanobacterium is capable of producing toxins, but only low levels of Anotoxin-A have been detected.  TKPOA has contacted the appropriate authorities, including Lahontan Regional Water Quality Control Board (LRWQCB). 

LRWQCB has recommended the placement of caution signs around the Tahoe Keys (attached) and regular monitoring.

Key precautions:

  • Avoid contact with algae or scum in the water
  • Keep children away from algae or scum
  • Fish caught in these waters should be cleaned with tap or bottled water.Guts should be thrown away
  • Do not let pets come into contact with algae / scum, drink the water or eat the scum on the shore
  • Do not drink lagoon water or use for cooking
  • Do not eat shellfish from the lagoons
